Thank you for viewing. This is a PORTER Tanker backpack. It is a discontinued item. Height: Approximately 40cm Width: Approximately 28cm Depth: Approximately 15cm A4 size fits. (Measurements are approximate. There may be some discrepancies.) I purchased this over 5 years ago and used it as a mother's bag. I haven't used it recently, so I'm putting it up for sale. - There is a red stain on the inside of the front pocket (the one with Velcro). (See photo 5) - There are scratches on the top and bottom of the main compartment, as if something sharp had pierced or snagged it. (See photos 17 and 18) As it is made of nylon, there is some shine from wear and tear, and some signs of use, but I think it is in relatively good condition. Please understand that this is a used item before purchasing.
